Enantioselective Construction of Spirooxindole-Fused Cyclopentanes
The Journal of Organic Chemistry, 2021The present study reports an asymmetric organocatalytic cascade reaction of oxindole derivates with α,β-unsaturated aldehydes efficiently catalyzed by simple chiral secondary amine. Spirooxindole-fused cyclopentanes were produced in excellent isolated yields (up to 98%) with excellent enantiopurities (up to 99% ee) and moderate to high ...

Diastereoselective Synthesis and Structure of Spirooxindole Derivatives
HETEROCYCLES, 2003Spiroindolinonisoxazolines (4 and 5h) are prepared from (E)- 1 or (Z)-3-arylidene-2-oxindoles (2) by nitrile oxide cycloaddition reactions. Only one regioisomer is detected in all cases, and the observed complete diastereoselection is established by unambigous structural assignments.

An Access to Highly Functionalized Dihydrobenzofuran Spirooxindole Scaffolds
Organic Letters, 2022We have developed an efficient protocol for the construction of polycyclic dihydrobenzofuran spirooxindole scaffolds via base promoted cascade annulation of Morita-Baylis-Hillman (MBH) carbonates of isatins with ortho-hydroxychalcones or ortho-hydroxy-β-nitrostyrenes. The complex polycyclic compounds were conveniently synthesized in satisfactory yields
